This is the fourth blog post in a series about Counting Principles. These principles are helpful when developing children’s number sense. It’s not enough for them to learn to count by rote, they have to develop a strong foundation of numbers and counting.

Cardinality is the fourth principle that I am taking a deep dive into.

You can see the other Counting Principle blog posts here.

What is Cardinality?

It is knowing that the last number that you said when counting is the number of objects in the set.

Why is Cardinality important?

Developing this number sense skill is important so that students can know how many objects are in a set and can compare two or more sets.

Activities to Work on Cardinality Skills

Counting sets of meaningful objects throughout the day will help students develop this skill. Model counting objects, then saying how many are in the set (“1,2,3 bananas. There are 3 bananas”).

Play dough mats, number puzzles, dominoes, are all great activities that will work on developing students’ cardinality skill. These blog post have some great counting ideas: number provocation, card center, math loose parts.

Laminate these clip cards and students can use clothespins to clip the correct number after counting the set (bonus- this works on fine motor skills too!)
